- Completion rate is a very poor metric to measure the 'success' of the concept. I attempted more than a dozen courses, but only completed ~4-5 of them. But that doesn't mean I didn't learn anything. For a number of courses, I got a good way through the material (75%+) but got distracted/side tracked (in one particular case, I was 90% of the way through a very challenging and interesting course[1] when a buddy and I decided to do a last minute trip to Mexico for some camping/surfing. Needless to say, it was hard to find internet access out there). Of the courses I completed, at least two of those I had to attempt more than once. But regardless of the final outcome, I learned a ton. There were a few courses that I didn't find interesting and walked away from, but for the most part, I learned something from every course, regardless of whether I completed it or not.
- By traditional metrics, I wasn't the best student in college. There were a number of reasons for this, but a key reason was the inability to focus during lectures. I just hadn't had enough life experience to learn how to optimize my ability to pay attention in class for multiple hours a day. In high school, the class sizes were small and the teachers were engaging enough to make it easy for me. In college (big public university) there were hundreds of students in each lecture and the professors were more interested in research than they were in lectures (with a few exceptions). I now know that I need the right balance of coffee, adequate sleep, and exercise in order to be able to sit through 4+ hours of very dry lectures, but it took years of hard won experience to find that balance. MOOCs are amazing because they let you optimize the 'lecture' time to best suite your schedule and your 'optimum time of focus'. And the forums were a great, asynchronous way to share knowledge between TA's and students (as opposed to my college experience where you had 1-2 office hours per week, with a dozen+ students competing for attention). Had MOOC-like teaching material (video lectures, forums, online exercises) been available when I was in college, I have no doubt that I would have done way better.
- Considering how expensive traditional college is getting, I think a very cool and plausible alternative would be to allow students to spend a few years doing internships/apprenticeships part time, and doing nano-degrees and MOOCs part time. A company could pay for the classes, as well as a stipend/salary for the internship. I learned programming and statistics on the job (seems like it's getting more rare these days for on the job training) but being able to take a step back and take more traditional classes on Coursera helped fill in some of the knowledge gaps that had been developing over the years. I feel like mixing both practical, in demand skills and theoretical knowledge at the same time could result in a much more engaging and deep understanding of the subject matter as opposed to the traditional way of all theory in college followed by all 'hands-on' in the real world.
Anyways, a bit of rant. But it's been a while since a MOOC post has made it to the front page of HN, and it's a holiday weekend!

I have a hunch that optometrists tend to slightly overprescribe the strength. Every time I would get a new prescription, I would walk out with superhuman vision, but than after a few days my eyes would adjust. At my last visit to the optometrist, I actually requested a lower strength and they obliged. And while I might have to squint here and there to read something really far away, I spend a good chunk of my time in front of computer, so I prefer the lower strength.
And I agree on increasing your eye strength as well. I try to take off my glasses frequently, and I have noticed that if I go for a while without them, my vision seems a little better when I put them back on. Also there are some apps that help as well [1]

Also, I worked in retail when I was younger. Most bigger stores keep an eye on the lines and will move more employees to the checkout registers if the lines are getting too long.
Regardless, for something like an election where so many factors can influence an outcome (turnout, late breaking news, biased polls) and with so few previous events to base your model on (~12 elections worth of data), you should heavily discourage your model from outputting such a high number. It is irresponsible considering what kind of an impact those types of forecasts can have on voter apathy and decision making, and the only reason I can think they did it was so that they could award themselves the 'most accurate forecaster' title after the election. But instead, they now get to award themselves the 'worst forecaster award', and the rest of us are stuck with Trump for 4 years.

1. Trump says something really bad 2. Check a poll aggregator (538) 3. Breath sigh of relief
For a good chunk of the election, Hillary had a really big lead in the polls. But after the Comey incident, things got tighter[1]. Nate Silver had some really good analysis on how tight the race was (a Trump win was within the polling error, and when state level polls are off, a lot of times they are all off in the same direction). But he was getting shouted down by the other aggregators. I was pretty on edge for this part of the race, but at the end, it looked like Hillary was picking up some momentum.
I think part of it was the bubble effect, but I also think Democrats put too much faith in these forecasts.
[1] At least on 538, a bunch of the other forecasters didn't budge. HuffingtonPost had a 98% chance of Hillary winning at the end. I really hope someone holds them accountable for that, as I wouldn't be surprised if such confident forecasts contributed to voter apathy.

1. Everyone I know who has managed this schedule has done so by negotiating with their existing employer (in my case a former employer). Doing this at the interview stage seems a sub-optimal (unless you are really in demand) because they will probably just go with someone else. After you have been working for a while, you are a known quantity, and so it's easier for them to stick their neck out for you. If your current employer is not receptive, you can apply pressure by threatening to leave (worked for a buddy, but you have to be prepared to walk). 2. For this arrangement to make sense, you really need to be good at setting boundaries. I was pretty bad at that, and as such, I often put in more hours. Part of the reason they took me on was because they were having trouble finding people to handle all the workload, so I should have realized that it would be a struggle to keep the workload manageable on the 75% schedule (when I used to work full time I put in a lot more than 40/week). 3. For me personally, I would much rather have a (very) flexible schedule than a shorter work week. I don't mind cranking out 10-12 hour days if needed, but I like the option to get some of that time back, whether it be taking part or most of a day off on short notice, or coming in late to the office in order to enjoy the outdoors in the AM or do some chores.
Due to 2 and 3, I think an hourly consulting arrangement would have been much better (for me at least). If you charge enough, you will make up for the lost benefits, and because you are charging hourly, you don't have to stress too much if the workload spikes from time to time because you will get paid for those extra hours.
Just to set the record straight, the solar industry would not exist without government support. Nearly every company past and present has taken grant money from the DOE, or directly benefited from cash rebates or stimulus money. Local utilities in many states are required by local regulatory agencies to buyback excess solar power at retail prices, which for many regions is the difference between hitting the break even point in a reasonable time frame. And before the ITC (tax credit) was unexpectedly extended last year, companies were preparing to downsize considerably and were warning local politicians that without an extension, there would be massive layoffs in the industry.
With battery tech starting to become viable and with continuing efficiency improvements, we are getting closer to a point where solar might be able to compete on it's own, but in it's current form, the industry is still highly dependent on subsidies and tax breaks.
And just because a company has defined salary ranges doesn't mean employees have no voice in the matter. If they feel those salaries are not keeping up with market rates, they can make that known to management, or they can go find greener pastures.
I think for very senior roles, individual negotiations still might make sense, as the value prop of those hires is highly variable and can have big impacts on the organization. But for roles like Software Eng I, and Software Eng II, etc... in the long run it is better for morale, attrition, and equality to use defined salary ranges. And you can still use bonuses to adjust compensation based on performance.
Gawker is a by-product of the current ecosystem that Silicon Valley has created. The rise of click bait journalism was a by product of incentives created by social media companies like Facebook. And Thiel sits in the center of this universe. If he really wants to be 'philanthropic' he should focus his efforts at the root causes of these issues. But he won't, because that is where his net worth comes from.
EDIT: To add a little more substance. I think the incoherence stems from the fact that the current conservative alliance is formed from approximately 3 distinct groups, with different priorities. You have the religious folks who care about abortion, same-sex marriage, drug laws, etc... And then you have the blue collar group that cares more about immigration, guns, etc.. And then you have the pro-business group which mostly cares about taxes and deregulation. From the outside looking in, it shouldn't be surprising that it's hard to empathize with the 'conservative' world view, because the external manifestations of that worldview are often very contradictory (i.e. why would a group that supports small-government also support the drug war, etc...)

And another thing to consider, for most homeowners a hot real estate market only benefits them if they are willing to move to a lower priced market or downsize their home. Moving laterally or trying to upgrade during a hot market means you are exposed to the same percentage of price increases as everyone else. The only people that really benefit from hot real estate markets are investors and landlords.
